| 摘 要： | 对柯坪地电阻率台整点观测数据进行FFT变换,计算出其年变周期约为305.5 d;分析了观测区地下水位、气温的变化以及下伏地层的影响系数与年变间的关系,最终明确柯坪地电阻率台观测数据的反常年变形态是由测区特殊的电性结构引起的。

| Abstract: | FFT is performed to the hourly sampled earth resistivity observations at the Keping Seismic Station, and its annual variation period is determined to be about 305.5 d. The relationship between the variation of groundwater level, air temperature, and the influence coefficient of underlying strata and the annual variation is analyzed. Finally, it is concluded that the abnormal annual variation of earth resistivity observations at the Keping Seismic Station is caused by the special electrical structure of the survey area. |
